SPOKE-TENONING MACHINE.

Specification of Letters Patent.

Patented Aug. 5,1913.

Application filed July 1, 1912. Serial N 0. 707,054.

To all whom it may concern Be it known that I, CHARLIE MUsE, a citizen of the United States, residing at Hartshorne, in the county of Pittsburg and State of Oklahoma, have invented certain new and useful Improvements in Spoke-Tenoning Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to wood working, and more especially to special machines for cutting the tenons on wheel-spokes; and the object of the same is to produce a portable and marketable machine for use in the smaller wagon shops, by means of which the inner ends of spokes may be cut to a bevel on their sides and with the proper shoulder on their edges so as to accurately fit the sockets in the hub. This and other objects are accomplished by constructing the machine as hereinafter more fully described and claimed, and as shown in the drawings wherein- Figure 1 is a front elevation of this machine complete, and Fig. 2 is a central vertical section on the line 22 of Fig. 1; Figs. 3 and 4 are horizontal sections on the lines 3-3 and 4-4 of Fig. 1 respectively.

The numeral 1 designates a base having a hole through it at a proper point, and at pposite ends of this hole 2 rise standards 3 and 4 having grooves 5 along their inner edges for guiding a cutter head 6 which by preference is a plate having a hole 7 through its body and a yoke 8 connected with its upper end. The yoke is centrally pivoted as at 9 to a lever 10 connected by a link 11 with the upper end of the standard 3 and by a link 12 with a hand lever 13 pivoted in the other standard 4, and when this lever is depressed the main lever 10 descends by reason of its link connection, and the yoke 8 forces the cutter head 6 downward within the guides within the standards in a manner which will be clear.

The numeral 14 designates a table mounted upon the standards at some distance above the base and provided with an opening 15 next the cutter head and with guides 16 between which slides the foot 17 of a gage 18, said foot having a fork 19 within which is swiveled a head 20 of a screw 21 whose threads engage a nut 22 carried by a lug 23 on the table, so that when the head of the screw is turned its swiveled end adjusts the gage 18 toward or from the cutter head 6 and across the table 14. Secured upon the base 1 beneath the table is an oblique-faced block 25 standing adjacent the hole 2; and against the outer side of the block rests a gage 26 whose foot 27 has slots 28 engaged by set screws 29 taking into the base so that the gage may be set toward or from the block 25 as will be clear. One end of the foot 27 is continued into an arm 30 upturned as shown and forked as at 31- the obvious purpose of this arm being to support the spokes when the inner end of the latter rests on the face of the block 25 preparatory to being cut to the proper bevel to fit the hole in the hub. It will be obvious that the spoke is beveled while it lies upon the block 25 at the lower portion of the machine, and, conversely, the spoke is tenoned while it lies upon the table 14 in a manner which will be made clear below.

The knife for beveling the end of the spoke is designated by the numeral 35, and by preference its cutting edge 36 stands oblique to a horizontal and is disposed over the hole 2 as shown, the body of the knife being adjustably bolted as at 37 to the lower edge of the cutter head 6 as indicated. The other knife 38 has one end or heel 39 turned at an angle to its body to form the shoulder when the edge 40 of this knife forms the tenon on the spoke; and the body of this knife is adjustably bolted as at 41 to the cutter head 6 at a point above the hole through said cutter head and on a line about even with the top of the table 14. Beneath said hole a chip-gage 45 is loosely attached at its center as at 46 to the cutter head 6, and is connected by four set screws 48 at its four corners therewith, so that when these set screws are adjusted the distance of the active edge of this gage from the face of the cutter head may be regulated at will. The function of this gage is to determine the thickness of the chips which will be cut out of the spoke by the edge of the knife 38, the chip of course falling through the hole in the cutter head and possibly through the other hole in the base and into a suitable receptacle or into the waste.

In use the machine is set up as shown in the drawings, and the inner end of the spoke is laid upon the face of the block 25 with its body resting in the fork 31 of the arm 30 at an oblique angle to the face of the gage,

and when the foot 27 of the gage 26 is adjusted properly by means ofits set screws, the inner corner of the inner end of the spoke will lie between the two standards 3 and 4. The hand lever is then manipulated to cause the main lever to descend, and the cutter head moves downward so that its blade 36 imparts the proper bevel to the edge of the spoke; after which the latter is reversed and the operation repeated. To adjust the angle or the thickness of the spoke at this point, the set screws through the foot 27 of the gage 28 can be set in a manner which will be clear, but the wedgeshaped block 25 and the position of the fork on the outer end of the arm 30 will doubtless remain the same, as they are merely for supporting the spoke while it is being out.

To shape the opposite side faces of the inner end of the spoke it is moved up onto the table 14. Here the gage 18 is set by turning the thumb screw so that the end of the spoke is fed as far toward the cutter head as necessary, and the gage is adjusted by setting its various set screws so that the pro-per depth of cut or notch will be made. The hand lever is then manipulated, the main lever 10 moved downward, and the cutter head descends to cause the knife 38 with its heel or angular end 39 to pass across the spoke, so that a chip of the proper size is cut therefrom and falls through the hole in the cutter head and into the waste; after which the knife is raised, the spoke inverted, and the operation repeated on the other edge. From time to time the knife blades will be removed and their edges sharpened as will be obvious.

All parts of this machine are simple in construction and accessible as for cleansing or repairs.

I do not limit myself to the sizes, shapes, proportions or materials, but would probably make most of the parts of metal for the sake of convenience and strength.

What is claimed as new is 1. In a machine for tenoning spokes, the combination with a base having an opening through it, a pair of guides rising from said base, a table carried by said guides and notched out between them, an oblique-faced block resting on the base, and adjustable gages on said base and table; of a cutter head movable vertically in said guides and having a hole through its body, a blade carried by the lower edge of said head and adapted to taper one side of a spoke when lying on said block, and a second blade carried by said head above the hole therein and comprising a knife with an angular heel adapted to cut a tenon on a spoke when resting on said table.

2. In a machine for beveling the inner ends of spokes, the combination with a base, a gage whose foot is adjustably mounted on the base, and an arm projecting from the foot and forked; of uprights rising from the base, a cutter head vertically movable between them, and a knife blade secured to the cutter head and moving past said gage, for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
